{"product_id":"4uantum-magnuspro-mcx-hopup-chamber-apfg-mcx-gbb","title":"4UANTUM Magnus Pro MCX Hop-Up Chamber for APFG MCX GBB Airsoft","description":"\u003cp\u003eMachined from a single billet of 6061 aluminum as a one-piece housing, the MAGNUS PRO MCX features our proven self-centering tri-lug design and true TDC adjustment mechanism. In addition to delivering improved accuracy and consistency, the chamber incorporates corrected cycling geometry. During operation, the chamber interfaces with the bolt carrier rather than the nozzle, helping prevent nozzle damage caused by repeated impact. Because the APFG MCX uses the Hop chamber as part of the barrel-mounting interface, the MAGNUS PRO MCX also improves overall structural rigidity through its stronger, precisely machined construction. The adjustment wheel is easily accessible through the handguard openings, allowing smooth incremental adjustments on the go—without disassembly or dedicated tools.\u003c\/p\u003e\n\u003cp\u003eInstallation references:\u003cbr\u003e✔ Compatible Models:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eAPFG MCX GBB series (Rattler, Legacy, SPEAR LT, Rattler LT, RSAR, SURG, MCX HUNTER models.)\u003c\/li\u003e\n\u003cli\u003eBPW MCX GBB series (With APFG MCX GBB system.)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e✘ Non-Compatible Models:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eAPFG XM7 (SPEAR) GBB (Different HOP-UP design.)\u003c\/li\u003e\n\u003cli\u003eAPFG MPX GBB series (Different HOP-UP design.)\u003c\/li\u003e\n\u003cli\u003eMCX GBB series from other AIRSOFT brands.
